Vedclass · Answer

(D) On moving down the group,as the atomic number of alkali metals increases,the number of shells increases,which leads to an increase in atomic radii. Although the nuclear charge increases,the shielding effect of inner electrons predominates,resulting in a larger atomic size. Thus,the correct order of atomic radii for alkali metals is $Cs > K > Na > Li$.

The atomic radii of the alkali metals follow the order
